Method for manufacturing a custom-circuit LSI, and a gate array device

摘要

A gate array is used as the base component of a custom-circuit LSI. A number of logic cells are arranged in the form of a matrix in the first area of the gate array. These logic cells are interconnected by a metal pattern or patterns to build a custom-circuit. Driver cells for energizing the output and input signals of the custom-circuit are formed in the second area of the gate array. Bonding pads, which will be used as the input/output terminals of the custom-circuit, are formed in the third area of the gate array.
